REV. 1.0.7
8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
NOTE: The GIE bit in the global register 0x80h must be set to "1" in addition to the individual register bits to enable the
interrupt pin.

BIT
NAME
FUNCTION
Register
Type
Default
Value
(HW reset)
D7
Reserved
This Register Bit is Not Used.
D6
DMO
Digital Monitor Output
The digital monitor output is always active regardless if the inter-
rupt generation is disabled. This bit indicates the DMO activity. An
interrupt will not occur unless the DMOIE is set to "1" in the chan-
nel register 0x04h and GIE is set to "1" in the global register 0x80h.
0 = No Alarm
1 = Transmit output driver has failures
RO
0
D5
FLS
FIFO Limit Status
The FIFO limit status is always active regardless if the interrupt
generation is disabled. This bit indicates whether the RD/WR
pointers are within 3-Bits. An interrupt will not occur unless the
FLSIE is set to "1" in the channel register 0x04h and GIE is set to
"1" in the global register 0x80h.
0 = No Alarm
1 = RD/WR FIFO pointers are within ±3-Bits
RO
0
D4
LCV/OF
Line Code Violation / Counter Overflow
This bit serves a dual purpose. By default, this bit monitors the line
code violation activity. However, if bit 7 in register 0x81h is set to a
"1", this bit monitors the overflow status of the internal LCV
counter. An interrupt will not occur unless the LCV/OFIE is set to
"1" in the channel register 0x04h and GIE is set to "1" in the global
register 0x80h.
0 = No Alarm
1 = A line code violation, bipolar violation, or excessive zeros has
occurred
RO
0
D3
Reserved
This Register Bit is Not Used.
D2
AISD
Alarm Indication Signal
The alarm indication signal detection is always active regardless if
the interrupt generation is disabled. This bit indicates the AIS
activity. An interrupt will not occur unless the AISIE is set to "1" in
the channel register 0x04h and GIE is set to "1" in the global regis-
ter 0x80h.
0 = No Alarm
1 = An all ones signal is detected
RO
0
